I need to migrate my mysql database from my myisam to innodb
But i dont have to do it for all the tables.. For some i would leave it as myisam and the others would be migrated to innodb.
Is there any particular mysql version criteria that i should look for to get the best performance and integrity?
Coud someone let me know of the process....

Well you can do this in the Query Browser (edit table) or via SQL:

ALTER TABLE `schemaname`.`tablename` ENGINE = MyISAM;

Well you cannot export the schema to csv ... you can export the content of your tables though ... or you export your schema, your data or both to an sql-script:
mysqldump --all-databases -u USER -p > all_databases.sql

above command will create an export of all tables and their content to a sql skript called all_databases.sql

You could have a look at liquibase. This makes really good snapshots of the Database Structure, all Constraints, Indexes ... everything ... except the Data itself, but I think you will be able to do that somehow. I just haven't tried that yet)
